Solution

Summaries and Symptoms

This patch updates the tools-light VIB to resolve the following issues:

  • Virtual machines with Linux guest operating system might stop responding due to kernel panic in balloon driver. You might see backtrace similar to the following:

    [ ] :vmmemctl:Balloon_QueryAndExecute+0x67/0x9cc
    [ ] :vmmemctl:OS_UnmapPage+0x102/0x2a0
    [ ] autoremove_wake_function+0x0/0x2e
    [ ] autoremove_wake_function+0x0/0x2e
    [ ] :vmmemctl:OS_UnmapPage+0x8/0x2a0
    [ ] kthread+0xfe/0x132
    [ ] child_rip+0xa/0x11
    [ ] keventd_create_kthread+0x0/0xc4
    [ ] kthread+0x0/0x132
    [ ] child_rip+0x0/0x11

    For details, see KB 2107363.

  • The vShield Endpoint drivers are renamed as Guest Introspection Drivers and two of these drivers, NSX File Introspection Driver (vsepflt.sys) and NSX Network Introspection Driver (vnetflt.sys), can be installed separately now. This allows you to install the file driver without installing the network driver.

  • When Unidesk is used in conjunction with VMview or vSphere with vShield Endpoint enabled, applications such as QuickTime might experience a slowdown in performance. This is due to an interoperability issue that gets triggered when Unidesk volume serialization filter driver and vShield driver is present on the stack. For each file opened by the application, even if it is just for reading the attributes, the vShield driver calls FltGetFileNameInformation causing further processing to be performed on the files. As a result Unidesk driver opens directories that causes an overall application performance degradation.

Patch Download and Installation

The typical way to apply patches to ESXi hosts is through the VMware Update Manager. For details, see the Installing and Administering VMware vSphere Update Manager.

ESXi hosts can be updated by manually downloading the patch ZIP file from the VMware download page and installing the VIB by using the esxcli software vib command. Additionally, the system can be updated using the image profile and the esxcli software profile command. For details, see the vSphere Command-Line Interface Concepts and Examples and the vSphere Upgrade Guide.
